Abstract

In view of the serious emulsification existing in Changqing condensate gas emulsion, the unclear oil-water interface and the poor application effect of demulsifier used in the field, it is urgent to study an efficient demulsifier. In this paper, PM and XP-1221 two kinds of demulsifiers are used to solve the emulsification problem. The PM demulsifier was compounded with XP-1221 chemical demulsifier to solve the emulsification problem of Changqing condensate. The effect of temperature and demulsifier concentration on demulsification performance was studied by bottle test method. The results showed that XP-1221 and PM could be effectively combined. The demulsification efficiency was high and the dehydrated water was clear. Studies have shown that XP-1221 has a good synergistic effect with PM. The suitable ratio of the composite demulsifier is 1:1, and the demulsifier effect of the demulsifier can meet the requirements of the oil field demulsifier. The composite demulsifier can meet the requirements of current oilfield demulsifiers.
